Steady poll lead continues for Alliance".

The centre-right Alliance's steady poll lead continues, with a new voter survey published on Wednesday giving them support of 49.8 percent of the voters. Support for the far-right Sweden Democrats also reached new highs.

Support for the centre-left Red-Green coalition came in at 40.9 percent, according to the poll, carried out by Synovate and published in the Dagens Nyheter (DN) newspaper.

The Sweden Democrats saw their support go from 6 percent last week to 7.5 percent, the party's highest level of support so far in a Synovate poll.

"Future surveys will determine if this is a randomly high result, but with a margin of error of 1.5 percent upwards and downwards, the Sweden Democrats are now between 6 and 9 percent," Synovate analyst Nicklas Källebring told DN.

And if the Synovate results correspond to the actual election results, the Sweden Democrats would find themselves with 27 seats in the parliament, making them the third largest party after the Moderates and the Social Democrats.
